ARM aims to shape IoT specs

ARM CEO Warren East announced that the IP chip vendor will join the Weightless Special Interest Group that is developing Internet of Things standards. The group was formed by Neul Ltd., a start-up company based in Cambridge, England.

Other members include Cable & Wireless Worldwide and CSR. The four companies have agreed on an approach for creating a new IoT standards and encouraging broad adoption. The new spec is expected to be ready in early 2013.

The group is aiming to deliver royalty-free, open standards to enable machine-to-machine (M2M) communications at the heart of the IoT. Communications among a basestation and thousands of machines is expected to use unoccupied TV transmission channels, so called white space radio. The platform could be used for multiple applications relying on M2M communications.

The reuse of white space spectrum offers a different balance between energy consumption and range compared to existing wireless standards. Cellular provides long range but consumes considerable energy and is optimised for low latency. Wi-Fi, ZigBee and Bluetooth offer longer battery life at progressively shorter ranges.

The Weightless spec will be optimised to fill this "connectivity gap," said East, adding that it could boost the range of M2M systems by several miles while providing ten-year battery life in a sub-Rs.108.70 ($2) radio.
